Detailed Description The MSL2164 and MSL2166 are highly integrated, flexible, 16-string LED drivers that use external MOSFETs to allow high LED string currents and/or voltage. They include power supply control to maximize efficiency and an advanced PWM dimming control circuit for regional dimming and 3D LED backlights. The drivers optionally connect to a video subsystem to offer a simple architecture for use in LCD TV backlight applications.
